Why Can the Aggregate Supply Curve Have Three Different Shapes 1. (b) of Figure 6 shows, because the firms are identical, the quantity supplied to the market is 1,000 times the quantity supplied by each firm. An Introduction to Short-Run Aggregate Supply. is equal to that portion of the short-run marginal cost curve that is above the average variable cost curve.
The quantity of output supplied to the market equals the sum of, the quantities supplied by each of the 1,000 individual firms,Thus, to derive the market supply curve, we add the quantity supplied by each firm in the market. Answer added by VENKITARAMAN KRISHNA MOORTHY VRINDAVAN, Project Execution Manager & Accounts Manager, ALI INTERNATIONAL TRADING EST.
As shown in figure equilibrium price and quantity are P 0 and Q 0, respectively. At that price, market demand is equal to the market supply. That is, as long as price is above average variable cost, each firm’s cost curve is its supply curve. Short run Equilibrium of the Industry Given the market demand and supply, the industry is in equilibrium at the price that ‘clears the market’. The market supply curve is found by adding the outputs of each firm at each price, as shown in Panel (b) of Figure 6.10 Marginal Cost and Supply. In the short run, when prices are sticky, an expansion in the money supply raises income.
any given price, each firm supplies a quantity of output so that its marginal cost equals the price, as shown in panel (a) of Figure 6. Continue Thus, the ISLM model shows that monetary policy influences income by changing the interest rate. THE SHORT RUN: MARKET SUPPLY WITH A FIXED NUMBER OF FIRMSĬonsider first a market with 1,000 identical firms.
